When the stationary case 10 is inserted into the insertion hole 2 with the mounting position secured, (10) is prevented from rotating. The fixed case 10 is firmly fixed by the fixed ribs 13. [ It is most preferable that the fixing ribs 13 extend along both side surfaces of the engaging jaw 12 as shown in Fig. A force is applied to prevent the detachment of the fixing case 10 in the thickness direction by the locking protrusion 12 and a force is applied to prevent the fixing case 10 from being rotated by the fixing rib 13, It is more firmly fixed.

The connection case 20 has a structure in which an upper case 21 and a lower case 22 are assembled to form an internal space.

The lower case 22 is formed with a plurality of fixing protrusions on the inner bottom surface so that the ground copper plate 23 can be fitted and fixed. A press-fit groove 22a is formed on the outer bottom surface of the lower case 22 so that a plurality of the fixing pins 40 can be inserted. The fixing pin 40 is composed of a body portion 42 that is press-fitted into the press-fit groove 22a and a head portion 41 that is formed to have an extended cross-section at an end of the body portion 42. The head portion 41 is smaller than the insertion portion 14b and has a larger cross-sectional area than the engaging portion 14a. The body portion 42 has a smaller cross-sectional area than the engaging portion 14a. A cable passage through which the power cable passes is passed through the lower case 22. The outer diameter of the lower case 22 corresponds to the inner diameter of the fixed case 10. A stepped portion 22b formed on one side of the upper case 21 is inserted and coupled to the other opening of the lower case 22.

The upper case 21 is formed with a step portion 22b on one side that is coupled to the lower case 22 and the step portion 22b is inserted into the lower case 22. One side of the upper case 21 is coupled with the lower case 22 to form a durable space and the other side is formed with an insertion groove 21c into which the cover 30 is inserted. An opening / closing member (50) for opening / closing the through hole (11) is rotatably mounted in the inner housing space of the upper case (21). A rotary shaft 21d protrudes from the central region of the upper case 21 and a rotary hole 51 of the gap member 50 is rotatably mounted on the rotary shaft 21d. At both ends of the opening and closing member (50), an inclined surface (52) for contacting the terminal plug of the outlet plug is formed. The inclined surface 52 is rotated when the outlet plug terminal rod is pressed, and the outlet plug terminal rod is connected to the ground copper plate 23 while the opening and closing member 50 is opened. The opening and closing member (50) is supported by a spring to maintain the through hole (11) closed.

In the central region of the ground terminal 70, a cutout groove 71 into which the rotary shaft 21d is inserted is provided. The ground terminal 70 is coupled to the upper case 21 to elastically support the opening and closing member 50. Since the opening and closing member 50 is resiliently supported by the ground terminal 70, it can be moved to some extent along the longitudinal direction of the rotating shaft 21d, thereby smoothly rotating. That is, when the outlet plug terminal rod presses the inclined surface 52 of the opening and closing member 50, the opening and closing member 50 is pushed backward by the pressing force at the same time as the opening and closing member 50 rotates naturally. At this time, since it is elastically supported by the ground terminal 70, it is moved along the rotating shaft 21d after the rotation is completed. The upper case 21 is formed with a through hole 21a through which the end of the ground terminal 70 protrudes.
